“ Cobalt at concentrations sufficient to stabilize HIF‐1α both oxidized intracellular ascorbate and induced an oxidant stress in the cells that was prevented by ascorbate.”
“Whereas the interaction of ascorbate and cobalt is complex, the presence of physiologic low millimolar concentrations of ascorbate in endothelial cells effectively decreases HIF‐1α expression and protects against cobalt‐induced oxidant stress.”
